Cuba's Bay of Pigs invaded once again - by millions of red, yellow and black landcrabs

It's happened again. Cuba's Bay of Pigs has been overrun, this time not by US-backed anti-Castro forces, but by millions of red, yellow and black landcrabs.

Each year, after the first spring rains, the crabs march for days from the surrounding forests to the bay on Cuba's southern coast to spawn in the sea, wreaking havoc along the way.

At dawn and dusk they emerge, scuttling sideways toward the sea, climbing up house walls and carpeting the coastal road that curves around the bay. The stench of crushed crab fills the air and their sharp shells puncture car tires.

"Thirty to 40 can enter without you even realising it," said Edian Villazon, who runs a food hut opposite the sea, which does not serve up crab meat. Cubans believe this type is toxic. "We have to always keep the door shut."

"It's very surprising and impressive to see so many crabs in one go and to watch them crossing so quickly," said 36-year-old French tourist Emilie Lannegrand, adding it was "a little heartbreaking" to see so many crushed on the road.

As cars speed by, some swerving to avoid the 10-legged crustaceans, the cracks of carapaces zing through the air.

That does not threaten the survival of the two prolific species, Gecarcinus ruricola and lateralis, which are not endemic to Cuba, said Jorge Luis Jimenez, a science ministry official who works in the park.

Similar crab migrations occur in other parts of Cuba at the same time of the year, as well as in some other special ecosystems such as Australia's Christmas Island.

At the Bay of Pigs, the adult crabs return to their forest burrows after releasing clouds of eggs and are joined a couple of months later by the baby crabs which hatched at sea, said Mr Jimenez.

For locals, the crab invasion is good business.

Ito Molina, 45, said tourists would happily pay $10 for tire repair, a princely sum compared with the average state salary of around $25 per month.

For patches, he applies condoms, which get put to many uses in Cuba given how cheap and readily available they are.

"All the cars pass along this road, and they all get punctures," he said. "So we stand there and repair the tires."
